Captain Bob reversed the change the same day: leave the word card exactly as v3, if a place to hook can be found. Records that there is one -- the call opcode, one place in the engine -- and what does not pass through it: 62 in-line words, EXECUTE, hand-written jumps, and call targets that are not dictionary entries. Notes that v3's TTL is computed from per-word heat. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
